GEORGE FORD, OF NEW lhdRllONY, INDIANA.

GATE.

SPECIFICATION forming part of Letters Patent No. 398,718, dated February 26, 1889.

Application filed January 16, 1888. Serial No. 260,812. (No model.)

To It u'hont it 'lII.'(l cour er/t.-

lie it known that I, hum-con. Ilouo, of New .lIa-rmony, in the county ol- Iosey and. Stat e of Indiana, have invented a new and useful Improvement in (lates, of which the following is a specification.

My invention .is an improvement in gates,

seeking to provide a simple construct-ion;

view of a gate constructed according to my invention. about line a it, hi 1. showing the inclines and the plate on which they are formed. Fig. I is a partial side view on an enlarged scale. Fig. 5 is a detail sectional view. Figs. (5 and 7 show dilferent inclines. Fig. 8 is a detail view of some of the connections, all of which will he (Ileseribed. Fig. 9 shows a slightly-different constructhm embodying my invention.

In carrying out my invention I provide on the gate inclines, and supports independently of such inclines, bearings thereftnywhich bearings are movable from their normal position rearwardly with reference to the direction of movement of the gate, and a l ifter for such gate. The gate comprises two sections, A A, and a conneeting-bar, I between such seetions,,on which connectionv I provide the inclines which inclines are preferably cast with and depend from a plate, I), secured to the under side of the connecting-bar and having a flange or portion, (1, to receive the bearing of the liftin-g shaft, presently described. The gate turns on a central post, E, which forms a support for a tube, F, which is provided with vertical slots G and inclined slots II. A lifting shaft or bar, g, extends at its ends through the vertical slots and engages the gate, preferably Fig. 2 is a detached section on Fig. 3 is a detail view I engaging the portion 1/ of plate I), as shown. The rod orhar l1 formsthebeariugs for the inclines ol' the gate, and is movable rearwardly from its normal resting point or position in the operation of the improvement. Ialso provide, in connection with the hearings, guides therefor, which guides are inclined upward, so that the hearings will be retracted when elevated, as will be more fully described. In the construction shown the rod or bar /1 extends through the slots II, which slots form inclined guides for the bearings provided at the ends of the rod or bar. The rods q 71 are connected together within the tube by providing them with bails g It, connected by links I i, which latter are connected by red or hanger J with the levers I\'.,by which the gate may be opened from either side. When the gate is at rest, as shown in full lines, Fig. i, the bearings h rest between two inclines say, for instance, I. and 2. Then if the gate be lifted vertically the bearings will be moved rearwardly with reference to the direction of movement of the gate and will pass to position to be engaged by incline marked 9, when the gate is lowered, as willbe understood from dotted lines, Fig. l. Then the hearing will move down its inclined guide, and the incline of the gate will move down its bearing to give the gate a quarter-turn.

'lhe inclined. guides, as shown. are preferred, as thereby I attain what may be termed a compound movement of the gate, part by the movement of the hearings in their guides and part by the inclines of the gate moving down such. bearings. If the inclines should be made as shown in Fig. 6, the bearings need be moved rearwardly but little, as most of the opening of the gate is done by the weight of the gate, its inclines moving down the bearings. If, however, the inclines are made as shown in Fig. 7, the hearings will have to be moved considerablyto the rear and upward, as the operation of opening will be effected almost entirely by the bearings passing down their inclines and carrying the gate with them.

If the slot (4 be made with an inclined portion, G, at its upper end, as shown in Fig. 9, it will serve to partially open the gate as the gate is raised, and the bearing 72. will not ICQ need to be moved so far rearwardly as in the construction shown in Fig. 4.

Having thus described my invention,what I claim as new is- 1. The combination of the gate having inclines, and bearings on which said inclines may rest and down which they may slide in the turning of the gate, said bearings being movable fronrtheir normal position in a direction reverse to that in which it is desired to open the gate, whereby as the gate is lifted the bearings may be moved from position to engage one incline to position for engagement by an incline in rear thereof, substantially as set forth.

2. In combination with a tube suitably supported and having an inclined or spiral slot inclined toward its upper end in a direction reverse to the direction of movement of the gate, the gate having inclines, a-.rod or bar movable in said inclined slot and extended to provide abearing for the inclines of the gate,

and a lifter fer elevating the gate and the rod,

gate, and a lifter for the said two shafts, substantially as set forth.

4. The combination, with a gate having in clines, of bearings for such inclines down which the latter may slide, such bearings being movable, and inclined guides for said bearings, whereby when elevated such bearings will be also retracted and the gate when lowered will be partially turned by the move ment of said hearings to their normal positions, and also by the sliding of its inclines 3 down said bearings, all substantially as and for the purposes specified.

5. The combination of a gate, a lifter for said gate, bearings onto which said gate is lowered after being lifted by the elevator, such bearings being movable from their normal position rearwardly with reference to the direction of movement of the gate, and inclined guides for said bearings, down which such bearings move in the operation of the invention, substantially as set forth.

6. The combination of the gate having inclines, the tube having vertical slots and inclined slots, the shaft having its ends extended through the vertical slots and engaging the gate, the shaft extended at its ends through the inclined slot in position to be engaged by the inclines of the gate, connections between such shafts, and means for elevating the same, substantially as set forth.

GEORGE FORD.
